The mini CORI-FLOW® series by Bronkhorst Cori-Tech B.V. are precise and compact Mass Flow Meters and Controllers, based on the Coriolis measuring principle. Designed to cover the needs of the low flow market, there are 3 models to overlap flow ranges from 5 g/h up to 30 kg/h (full scale values), each offering “multi-range” functionality: factory calibrated ranges can be rescaled by the user, maintaining the original accuracy specs. As a result of this, customers are able to reduce the variety of instruments and thus reduce the cost of ownership. The instruments are equipped with a robust IP65 weatherproof housing and are available with ATEX approval for use in Zone 2 hazardous areas.

Product Information

The new digital MASS-STREAM® series D-6300 works on the basis of direct through-flow measurement, following the constant temperature anemometer principle, and will replace the current analogue series D-6200 on a mid term view.

The MASS-STREAM® series D-6300 is characterised by significant improvements, covers flow ranges from 0.01…0.2 ln/min up to 100…5000 ln/min (Air), and follows M+W’s strategy of widely standardised product ranges. The instruments have IP65 protection as a standard and are operated with a main-board with all functions for accurate flow measurement and control. They can be supplied with commonly used digital or analogue input/output signals. Along with the standard RS232, Profibus-DP, DeviceNet, Flow-Bus and ModBus-RTU are available as an option.

One key element and innovative improvement is the optionally integrated, modern, multi-functional and multi-colour display, fully IP65 compliant with operator buttons on the instrument. With its multiple functions, such as actual flow indication, totalisation and alarms, the new MASS-STREAM® series D-6300 offers an excellent price-performance ratio. The instruments are suitable for application in laboratories, production machinery as well as industrial installations.

Features:

• Useable for virtually every kind of gases
• Compact and robust IP65 design
• Very low pressure drop
• Measurement without moving parts
• Less sensitivity to humidity or dirt
• No inlet pipes needed
• Optional with integrated TFT display
  • multi-functional: actual flow, totaliser, alarm etc.
  • operator button on the instrument
  • IP65 compliant
• Maintenance-free
• Body material in Aluminium or Stainless Steel

D-51xx - D-62xx Product Information

The new MASS-VIEW® flow meter series are a digital alternative to the conventional VA meters (variable area meters) or rotameters. The MASS-VIEW® flow meter series incorporates a digital bar graph of actual gas flow, which is, thanks to the OLED (organic light emitting diode) technology, clearly visible from all angles, as well as indicating flow units, gas type and totalised figures. Also available with an optional in-built needle valve for flow control duties, it is designed to mimic the straightforward features and vertical format of the VA meter, but with the considerable added benefits of an electronic output signal, high measuring accuracy, virtual independence from gas temperature and pressure variations, freedom from parallax error and inherently safe construction, by eliminating fragile glass components in the flow path.

The MASS-VIEW® series operates on the principle of direct thermal mass flow measurement, for gas flow ranges from: lowest range 0-0.2 ln/min up to highest range 0-200 ln/min* * ln/min equals SLM at 0°C and 1 atm (STP)

It offers a standard accuracy rating of ± 2%RD if the flow is higher than 50% of it’s maximum full scale and ±(1%RD + 0.5%FS) on lower flows, handling pressures up to 10 barg (150 psi). Power consumption is low and mechanical process connections are fitted for straightforward VA meter replacement. The MASS-VIEW^® incorporates the latest OLED technology, which gives a brighter readout than LCDs, can be viewed from virtually any angle and has fast signal response times. Alarm settings and the selection of a pre-installed gas or pre-set range are accessed via a user-friendly menu, using a 4-way navigation button mounted on the front plate. An analog output signal enables data logging against various parameters and full accountability of gas flow, such as for shared ring main applications.

Features

• Clear indication in:
  - actual flow rate (bar graph and value)
  - desired flow units
  - type of gas
  - totalized flow
• Bright, wide-angle OLED display
• Free of parallax errors
• Virtually independent of pressure and temperature variations
• Low pressure drop
• Wide flow ranges
• Fast response
• High accuracy
• Alarm and counter functions (2 alarm contacts available on meters)
• Analog (0..5 Vdc) and digital communication (Modbus-RTU, RS-232 interface)
• Configurable password protection
• 7 pre-installed gases available (Air, N₂, O₂, Ar, CO₂, CH₄, C₃H₈) or H₂ or He
• 4 selectable ranges (100%, 50%, 25% and 10% of maximum full scale range)
• Digitally calibrated
